I have a CentOS 5.2 PC with Grub. Output is redirected to a serial console.
A snippet of my grub.conf:
title CentOS (2.6.18-92) root (hd0,0) kernel /boot/vmlinuz-2.6.18-92 ro root=LABEL=/ console=ttyS0,9600 initrd /boot/initrd-2.6.18-92
During boot up, normally the system shows "Uncompressing Linux..." and a few grub.conf lines on the VGA console. Thereafter the output is redirected to the serial console.
However on this system, VGA shows just a "Starting up" line - serial output looks okay and the rest of the system seems fine.
Why is there a difference in the VGA output?
